According to the definition of the International Organization for Standardization (ISO), Fine Bubbles are bubbles with a diameter of less than 100 micrometers in a liquid, which can be further divided into two types based on their size: Micro Bubbles (MB) and Nano Bubbles (UFB). The reason why micro nano bubbles are classified separately is that they have completely different characteristics from the commonly seen millimeter sized microbubbles
What are micro nano bubbles
According to the International Organization for Standardization(ISO)Definition of micro nano bubbles(Fine Bubble)It means that the diameter in the liquid is smaller than100Micro sized bubbles are further divided into micro sized micro sized bubbles based on their size(Micro-Bubble;MB)And nano sized nano bubbles(Ultrafine-Bubble;UFB)Two types. The reason why micro nano bubbles are classified separately is that they are similar to the commonly seen millimeter sized microbubbles(Milli-Bubble)Having completely different characteristics, see figure2.

In recent years, many excellent functions of micro nano bubbles have been discovered, such as large specific surface area, long residence time, and interfacezetaHigh potential. In addition to its inherent properties, the effects generated by these properties are also significant, such as self pressurized dissolution, generation of free radicals, and enhanced mass transfer efficiency. Therefore, micro nano bubbles have been well applied in many fields such as environmental protection, agriculture, film production, medical diagnosis and treatment, flotation, sewage treatment, soil improvement, oil recovery, and metallurgical industry. They have developed rapidly in countries around the world such as the United States, Japan, China, and Germany, with a trillion dollar market potential.
2013In the year, the International Organization for Standardization(ISO)Establish a new technical committee-Microbubble Technology Committee and corresponding standard groups:ISO/TC281.2018year10In September, the Micro Nano Bubble Professional Committee of the Chinese Particle Society was established.2019year11In September, the National Standardization Management Committee decided to establish the National Fine Bubble Technology Standardization Committee.
ZYWNP-WJS-1Real time dynamic observation system for underwater online micro bubbles
The application scenarios of micro nano bubble technology are extremely diverse, including aquaculture, cultivation, irrigation, fertilization, membrane bioreactors, plastic containing wastewater treatment, stabilization ponds, urban sewage treatment, and solid waste water treatment-Liquid and liquid-Liquid separation wastewater treatment equipment, dairy factory wastewater, meat processing plant, golf course pond, brewery wastewater treatment, aerobic mud bacterial decomposition tank, shrimp farm, pond lagoon, algae control, cattle farm, fish transportation, fish preservation, environmental protection, agriculture, flotation, wastewater treatment, soil improvement, vegetable planting, soilless cultivation, nano bubble showerhead, nano bubble faucet, medical, health and wellness, and more.
Because micro nano technology has a wide range of applications, diverse preparation methods, and various equipment, the performance and utility of micro nano bubbles vary greatly depending on their diameter. Therefore, people urgently hope to have equipment for detecting the diameter of micro nano bubbles. There are currently some laboratory instruments that can detect the diameter of micro nano bubbles in water samples, butWhen micro nano bubble water samples are taken out from entities in scientific research and production practice and sent to the laboratory, micro scale bubbles are basically lostNano scale bubbles also experience partial loss and state changes, and the detection results cannot reflect the true functional state of micro nano bubbles in water bodies used in scientific research and production. This results in a lack of real-time data support for scientific research, making it impossible to quantify the effectiveness of bubble size control in production practice.
JXWNP-WJS-1The underwater online micro bubble real-time dynamic observation system (nano bubbles have other models) is designed to solve the problem ofUnderwater, online real-time, dynamic, and identifiableA detection device developed based on these keywords.
JXWNP-WJS-1The underwater online micro bubble real-time dynamic observation system is suitable for fluid environmentsObserve suspended micrometer sized particles, colloids, and bubble like substances online, continuously, and in situDue to the use of microscopic imaging technology, the detection result * is“What You See Is What You Get”Not only is the data authentic and reliable, but it can also distinguish particles, colloids, and bubbles. For example, when measuring bubbles, the "pore containing automatic segmentation analysis" method can be used to automatically eliminate solid particles, colloids, and other interfering substances. The deviceGreatly enriched the observation and testing methods for volatile samplesHelp us understand the generation, motion, and mode of action of such small objects more easily.
This equipment is also widely used in various liquid particle suspension systems in the fiber industry, oil and fat, papermaking, ink, food, rubber, synthetic resin, pharmaceuticals, oil extraction, petroleum and other polymer industries. It is a new means for universities, industrial and mining enterprises and other units to monitor and control product performance online in scientific research and production practice, stabilize and improve product quality.
This device has the characteristics of compact structure, easy use and maintenance, rapid observation, and reliable results.
